Abstract

本発明は、軸内にあり且つ回転する構成要素、特に乾式機械加工（ＭＭＳ技術）及び湿式機械加工用工具構成要素を解放可能に且つ固定状態で嵌合させる結合機器のクランプ要素に関し、この要素は結合される構成要素間に摩擦式の結合を提供する。結合機器の中心に配置される冷却管（２）は、クランプ要素の形状寸法を修正する。スピンドルには液体冷却管（２）によって貫通する長手状穴が設けられ、従って、クランプ部（５）の半径方向の偏りが補償される。基体（７）及びクランプ部（５）間におけるクランプ部の修正構成は、クランプ部（５）の支持のための力の配分が増加されることを可能にする。クランプ部（５）の新規な形状寸法は結果的に、より平滑な移行部分を備えた基体の新規な外形となり、それ故、より良好な力の配分が得られて、材料の破損が低減させられると共に、より信頼のある且つ頑丈なクランプが得られる。その新規な形状寸法のため、クランプ部（５）はより大きな締付ねじが載置されることを可能にする増大した面を有する。締付ねじ（８）は新規なクランプ要素、スピンドル（３）及びクランプ部（５）が半径方向に偏らされることを可能にする。スピンドル（３）は締付ねじ（８）及びクランプ部（５）の間に据え付けられており、結合機器がクランプされる時に、締付ねじ（８）のねじ込み端により多くの係合ねじピッチ長（１０）を有することにより、クランプ安定性が増加する。  The present invention relates to a clamping element of a coupling device for releasably and fixedly fitting a component that is in-shaft and rotates, in particular dry machining (MMS technology) and wet machining tool components. Provides a frictional coupling between the components to be coupled. A cooling tube (2) located in the center of the coupling device modifies the geometry of the clamping element. The spindle is provided with a longitudinal hole that is penetrated by the liquid cooling tube (2), thus compensating for the radial deviation of the clamping part (5). The modified configuration of the clamping part between the base body (7) and the clamping part (5) allows the distribution of forces for supporting the clamping part (5) to be increased. The new geometry of the clamping part (5) results in a new outer shape of the substrate with a smoother transition part, thus providing a better force distribution and reducing material breakage. As well as a more reliable and robust clamp. Due to its novel geometry, the clamping part (5) has an increased surface that allows a larger clamping screw to be mounted. The clamping screw (8) allows the novel clamping element, spindle (3) and clamping part (5) to be biased radially. The spindle (3) is installed between the clamping screw (8) and the clamp part (5), so that when the coupling device is clamped, the threaded end of the clamping screw (8) has more engagement screw pitch length. By having (10), clamp stability increases.

本発明は回転し且つ軸内にある構成要素、特に工具構成要素を対応する支持部品に、例えば工具ベース受け入れ要素上に解放可能に且つ固定状態で嵌合させる結合機器のクランプ要素に関する。   The present invention relates to a clamping element of a coupling device that rotates and lies in a shaft, in particular a tool component, in a releasably and fixedly fitted manner on a corresponding support part, for example on a tool base receiving element.

本発明はワーク又はワーク支持部品、例えば工具ベース受け入れ要素の形態をなす工具システムモジュール、及び結合される操作機器、例えばドリル加工、ターニング加工又はフライス加工機械として構成される機械工具の間の結合機器に関する。それ故、結合機器は固定式及び移動式、例えば回転ワーク又はワーク支持部品、例えば工具システムモジュールの両方で使用される。クランプシステムは２個の好適に回転する対称構成要素の解放可能な連結のために使用され、その中の幾つかは好適に円柱状又は円錐状の中空軸を有し、また幾つかは中空軸を受け入れるために対応する受け入れ部を有することにより、精確な嵌合が存在する。クランプシステムは受け入れ部の中心に配置されるクランプ機器を含み、クランプ機器は両方の構成要素が合わせて結合された時に、一方の構成要素の中空軸まで延出すると共に、反対方向に移動する少なくとも２個のクランプ体及びクランプ体を駆動する駆動機器を有し、この駆動機器によってクランプ体が同時に移動させられて、中空軸のアンダーカットクランプ肩部に対して係合及び解放することにより、結合される構成要素の平坦な面間における接触力が保証される。本発明によれば、クランプ要素は半径方向への摺動移動を有する。   The present invention relates to a coupling device between a workpiece or a workpiece support part, for example a tool system module in the form of a tool-based receiving element, and an operating device to be coupled, for example a machine tool configured as a drilling, turning or milling machine About. Therefore, the coupling equipment is used both stationary and mobile, for example rotating workpieces or workpiece support parts, for example tool system modules. The clamping system is used for the releasable connection of two suitably rotating symmetrical components, some of which preferably have a cylindrical or conical hollow shaft, and some are hollow shafts By having a corresponding receiving part to receive the, there is an exact fit. The clamping system includes a clamping device disposed in the center of the receiving portion, the clamping device extending to the hollow shaft of one component and moving in the opposite direction when both components are joined together. It has two clamp bodies and a drive device that drives the clamp body, and the clamp body is moved simultaneously by this drive device to be engaged and released with respect to the undercut clamp shoulder of the hollow shaft. The contact force between the flat surfaces of the components to be produced is guaranteed. According to the invention, the clamping element has a sliding movement in the radial direction.

クランプシステムは、特許文献１に開示されるように、高速及び２個の構成要素間の解放可能な連結に関連する。機械工具及び工具モジュール間における境界面領域の極めて充分な結合は、特許文献２及び特許文献３、並びに特許文献４及び特許文献５に記載されており、重要なこととしては、連結される構成要素は確実に且つ固定状態で合わせて把持されることである。

本発明は上記した懸案を解決するためになされたものである。   The present invention has been made to solve the above-mentioned concerns.

上記した課題を解決するために、本発明は請求項１に記載した手段を採用している。   In order to solve the above-described problems, the present invention employs the means described in claim 1.

本発明によれば、クランプ要素１は乾式機械加工、例えば（ＭＭＳ技術）並びに湿式機械加工用に提供され、この要素は結合される構成要素間に最適な摩擦式連結を提供する。結合の中心に配置される冷却管２は、クランプ要素の形状寸法を変化させる。スピンドル３には長手状穴があり、冷却液管はこの長手状穴を通り案内される。スピンドルの長手状穴４は、クランプ部５の半径方向への撓みを補償する半径方向クリアランスを有する。基体及７及びクランプ部５間におけるクランプ要素の可変構成に起因して、クランプ部を支持するための力の配分がより大きくなる。次に、クランプ要素の新規な形状構成は、より
平滑な移行部分を備えた新規な外形、それ故より良好な力の配分をもたらし、複数の要因による材料の破損を減少させると共に、確実な或いはより一層の把持が補償される。 According to the invention, the clamping element 1 is provided for dry machining, for example (MMS technology) as well as wet machining, which provides an optimal frictional connection between the components to be joined. A cooling tube 2 arranged in the center of the coupling changes the geometry of the clamping element. The spindle 3 has a longitudinal hole, and the coolant pipe is guided through this longitudinal hole. The longitudinal hole 4 of the spindle has a radial clearance that compensates for the bending of the clamp part 5 in the radial direction. Due to the variable configuration of the clamping element between the base body 7 and the clamping part 5, the distribution of the force for supporting the clamping part is greater. Secondly, the new geometry of the clamping element results in a new profile with a smoother transition and therefore better force distribution, reducing material breakage due to multiple factors and ensuring More grip is compensated.

その可変構成に起因して、クランプ部はより大きな締付ねじ８が嵌合させられることを可能にするより大きな面を有する。クランプ要素は締付ねじによって、半径方向に偏らされる。   Due to its variable configuration, the clamping part has a larger surface that allows a larger clamping screw 8 to be fitted. The clamping element is biased radially by a clamping screw.

スピンドルは締付ねじ及びクランプ部の間に位置されており、連結器がクランプされる時に、締付ねじのねじ込み端に、より多くの係合ねじ回転１０を有することにより、クランプ安全性が増加する。   The spindle is located between the clamping screw and the clamping part, and has more engagement screw rotation 10 at the threaded end of the clamping screw when the coupler is clamped, thereby increasing clamping safety. To do.
